Large number of people in the country still use handpumps to meet their drinking water requirements. But anyone who has tried to use hand pumps single handedly to drink water directly from the taps knows how difficult it is to pump and store water in the spout of the pump at the same time. While in some of the modified pumps, the handle has been fitted on the same side as the delivery pipe, the problem still remains because the output is much more than can be consumed using hands. The result, therefore, is that lot of water is wasted.
Attach a valve and a tap on the delivery pipe so that one can pump and store the water in the body and the outlet pipe. And after pumping enough water, one can go to the other side, unscrew the tap and drink water with as much flow as one can conveniently drink with the hands. With increasing water scarcity, saving every drop matters apart from increasing the convenience of using the tap.
